Sparrow Wallet releases v2.5.4 security update, independent verification scope expanded

According to Bitcoin News, Sparrow Wallet v2.5.4 has been released after extensive AI-assisted review, featuring multiple security enhancements aimed at reducing user reliance on external servers like Electrum.

Additionally, this version strengthens Ledger, Keycard, Trezor, Payjoin, PSBT, and multi-signature handling, removes Bitcoin Core credentials and other confidential information from debug logs, restricts existing wallet and backup directory permissions to owner access only, closes local DNS resolution leaks when using Tor, and enhances wallet import, signing, downloading, and server response validation. This update expands Sparrow Wallet's scope for independently verifying transaction data, hardware devices, and other inputs, reducing reliance on external servers for data provision.
